HINGE.

SPECIFICATION formingpart of Letters Patent No. 618,668, dated January 31, 1899.

Application tiled December 9, 1897. Serial No. 661,271. (No model.)

T0 all whom it may concern: v

Be it known that IVILLIAM H. HART, a citizen of the United States,residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Hinges, of which the following is a specification.

My invention relates to improvements in hinges of the class designed to be secured in place within holding-mortises; and t-he main objects of my improvement are to produce such a hinge of superior strength and ex' tended holding-faces in proportion to the weight of the hinge and to produce a hinge from a series of lapped plates with the outer ends of both leaves of the same dimensions in the direction of the pintle as the knuckle portion of the hinge.

In the accompanying drawings, Figure 1 is a side View of my hinge together with two blocks hung together by means of said hinge. Fig. 2 is an edge view of said hinge. Fig. 3 is an end view. Fig. 4 is a plan view of the blank from which the leaves of said hinge are made. Fig. 5 is an edge view of a like hinge with an additional plate in one of its leaves; Fig. 6 is a sectional view of the same on the line c t of Fig. 5. Fig. 7 is an edge View of my hinge with a third plate added to one of the leaves at one side instead of in the middle. Fig. 8 is an end View of the same. Fig. 9 is a side view of one leaf of my hinge of a somewhat different form. Fig. 10 is an edge view of the same; and Fig. 11 is a plan View of the main portion of the blank from which the hinge leaf, Figs. 9 and 10, was formed.

A A designate two blocks of wood suitably mortised, with my hinge applied thereto by driving the hinge into said mortises in the endwise` direction of the pintle. One leaf (the left-hand leaf of Figs. 1 and 2) is composed of two straight plates 12 and integral end connection 13, v'while the companion leaf is composed of a like integral end connection 13 and two offset plates 14. The body of each nections 13.

tion which lies between the in ner faces of the two plates of each leaf is bent on each side of its middle toward the knuckle or pintle end of the leaves, so as to bring the edges 17 of said portion flush or even with the faces -1S ofthe holding-wings. These leaves are formed from a straight flat blank, as shown in Fig. 4, in which I have given the parts the saine reference-numerals in so far as they are applicable thereto. The blank is slit transversely, as at 19, to divide the edge 17 from the holding-wings 1G, and the blank is doubled upon itself-on two lines near the saidv slits, and then the edges 17 are bent-to the form shown, dressing said edges, if necessary, to make them even with the face of the holding-wings. It is preferable to make the middle portion of the blank slightly wider than` the rest, as shown lin Fig. 4, sov as to avoid too much stretching of the metal in bringing the edges 17 into the plane of the face 18 of the holdingwings 16.

If the end connections are so long as to leave a space between the knuckles 15 of the leaf having the offset plates 14, a disk or washer 20 may be placed between said knuckles to fill said space, as shown in Fig. 2. The knuckles 15 of the oset plates 14 are passed inside ofthe knuckles 15 of the straight plates 12, as shown in Figs. 2 and 5, and the two leaves are secured by an ordinary pintle 21.

In Figs. 5 and 6 I have shown a hinge substantially the same as that shown in Figs. 1, 2, and 3, excepting that a plate 22 is substituted for the washer 20. This is a iiat plate witha disk-like knuckle 15 and holding-wings 16, the edges 17 being notched on each side of the middle portion of the end connection- 13a, while the end of said plate is notched to receive said end connection, as shown in Fig. G. This gives a hinge with three plates in one if the leaves and two plates in the companion eaf. l

AIn Figs. 7 and 8 I have also `shown a hinge with a like number of plates in its leaves; but instead of putting the additional plate in the middle I have added the plate 23 to one side. The straight plates 12 and end connections are the same as the plates 12 of Figs. l to 6 except that the end connections are shorter IOO holding-face.

and that a shallow recess 24 is made at the outer end of one of the plates for the reception of the spacing and connecting stud or lug 25 of the plate 23, as shown in Fig. 8. Said plate is also provided with holding-win gs 1G, the faces of which are in the saine plane as the holding-faces 18 of the wings 16.

The hinge-leaf of Figs. 9, 10, and l1 is composed of two straight plates l2, with an integral end connection 13b and holding-wings that are equally applicable to a leaf having the offset plates. These plates have the same form of body, disk-like knuckle l5, substantially the same holding-wings 16, only their holding-faces 1S are nearer the outer ends of the plate and even or substantially even with the surface of the metal on the inside of the end connection 13", which en'd is not slit for bending its edges inwardly, but is left solid and substantially flat for the whole width and length ofits inner face. As in the hinge shown in Figs. l, 2, and 3, the holding-faces of the wings and bearing-face of the end connection are in one plane, so as to form a continuous The blank for two such plates and end connection is shown in Fig. ll. The same blank may be used for the two connected offset plates, or all of the blanks may be first formed into straight plates, as in Figs. 9 and l0, and then part of said plates may be offset like the plates 14, before described. These plates can be assembled into a hinge in the manner herein described for either of the hinges illustrated.

By my improvements I make a hinge of this class that is very strong, has broad holdingfaces, and the outer ends of both leaves may be made of the same dimensions in the direction of the pintle as the knuckle portion of the hinge, so that a single fiat pressing-face may be used for simultaneously forcing both leaves of the hinge into its mortises in the blocks or parts to which the hinge may be secured.

It is apparent that in carrying out my invention some changes from the construction herein shown and described may be made, and I would have it understood that I do notlimit myself to the exact form shown, but hold myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

I claim as my inventionl. A hinge the leaves of which have two plates the broad faces of which plates are arranged at a right angle to the hinge-pintle with integral end connections extending in the same general direction as said pintle and holding-wings at the outer ends of each leaf substantially as described.

2. A hinge the leaves of which have two plat-es with integral end connections and holding-wings at the outer ends of each leaf, the inner faces of the wings and inner bearingface of the end connections forming a continuous face from the outside of one plate to the outside of the other plate su bstantially as described.

3. A hinge the leaves of which have two plates the broad faces of which plates are arlranged at a right angle to the hinge-pintle with integral end connections at the outer ends of said leaves and separate knuckles at their inner ends, the plates of one leaf being offset to permit their knuckle ends to overlap while the end connections between the plates are of the same length in both of said leaves.

4. A hinge,one leaf of which has two straight plates the broad faces of which plates are arranged at a right angle to the hinge-pintle with integral end connections at the outer ends of said plates and the other leaf of which has offset plates with integral end connections at the outer ends of said plates, the knuckles of said two leaves being united by a common pintle with the outer ends of both leaves of the same dimensions in a direction transversely to the broad sides of the plates of which said leaves are formed the broad flat faces of said outer ends and knuckle at each end of the pintle being in one plane substantially4 as described.
